Finding Engine Family Numbers


In order to find the Engine Family Number on your vehicle, locate your engine nameplate.  Generally the nameplate is permanently affixed to the engine.  The exact appearance of the nameplate varies by engine manufacturer.  For non-California engines, the Engine Family Number will be replaced by an EPA Number.

The Engine Family Number is a 12-character number/letter designation included on the engine nameplate for all heavy duty truck engines sold in the United States. Here are 2 examples of Engine Family Numbers for which the Econix DPF-A is verified:  A) 1997 International Engine with 7.3 liter displacement: VNV7.3C8DAAW; and B) 2002 Cummins Engine with 5.9 liter displacement:  2CEXH0359BAB.

Providing a list of Engine Family Numbers is the required first step in starting your DPF purchase process, because all DPF verifications from CARB (California Air Resources Board) are based specifically on Engine Family Numbers.
